      MIPS: make possible board-specific header files

      This patch makes possible to put a board-specific
      header file (e. g. foobar.h) to arch/mips/boards/*/include/board/.

breaks the out-of-tree build for the boards that use it (rzx50).

Depending on the SoC a barebox.bin, barebox.netx, barebox.s5p, MLO image
is generated. With pbl support there now is an additional
arch/arm/pbl/zbarebox.bin image.

To help the user to determine which image should be flashed to his device,
generate a barebox-flash-image link.

blackfin, mips, openrisc, ppc, sandbox, x86: add generic dma_alloc, dma_free inlines ...

Some drivers call dma_inv_range() on buffers, on arm these buffers must
be cache line aligned. This patch introduces a generic dma_alloc,
dma_free. Archs can implement in their own functions in "asm/dma.h" and add a:

	#define dma_alloc dma_alloc
	#define dma_free dma_free

On all other archs the generic versions, which translate into xmalloc
and free are used.

The 40 KHz frequency value was used to parry
__lshrdi3() error on little-endian MIPS because

The true value of the JZ4755's external clock frequency is 24 MHz.

MIPS: XBurst: suitable solution for per-board debug_ll ...

In the commit 40492a0
(MIPS: add common header file for DEBUG_LL via NS16550)
introduced common DEBUG_LL via NS16550 for MIPS
(see file arch/mips/include/debug_ll_ns16550.h).

In the commit 1cbe2b2
(MIPS: XBurst: add Ritmix RZX-50 board support)
the file debug_ll_ns16550.h used in
the file arch/mips/mach-xburst/include/mach/debug_ll.h.

Usage looks like this:

------------------------------------------------
+#ifdef CONFIG_BOARD_RZX50
+#include <mach/debug_ll_jz4755.h>
+#endif
+
+#include <debug_ll_ns16550.h>
------------------------------------------------

So after adding another board (e.g. A320) we will have something like this:

------------------------------------------------
 #ifdef CONFIG_BOARD_RZX50
 #include <mach/debug_ll_jz4755.h>
 #endif

+#ifdef CONFIG_BOARD_A320
+#include <mach/debug_ll_jz4740.h>
+#endif

 #include <debug_ll_ns16550.h>
------------------------------------------------

This approach has disadvantage:
* the files mach/debug_ll_jz4740.h and mach/debug_ll_jz4755.h
(they go to arch/mips/arch-xburst) are __BOARD-SPECIFIC__
(not SOC- or mach-specific!); The file mach-xburst/include/mach/debug_ll.h
is outside board directory, but it contains some board related information.

This commit introduce a more suitable solution.
